More suicide attempts are made during adolescence than at any other time in life. However, the measurement of suicidal ideation in adolescence has been hampered by a failure to understand the fine-grained aspects of suicidal ideation that predict the transition from suicidal thoughts to actual suicidal behavior. Recent research suggests that knowing how adolescents think about suicide – i.e., the form of suicidal ideation – in terms of characteristics such as frequency, duration, and pattern – may help predict not only whether an adolescent will go on to make a future attempt but also how soon they will do so, regardless of whether they have previously made a suicide attempt. However, current suicidal ideation measures and conceptualizations of suicide risk tend to ignore the form of an adolescent's suicidal ideation. This proposal for a renewal of a SCORE SC1 grant seeks to test 1) whether suicidal ideation that is characterized as occurring within a more persistent, long-standing episode is associated with higher short-term risk for a future suicide attempt over a 12-month follow-up period, compared to suicidal ideation that occurs in the context of a brief episode; 2) whether chronic suicidal ideation is characterized by more interference from and difficulty disengaging from suicide-related thoughts, as assessed by laboratory measures; and 3) whether this interference from and difficulty disengaging from suicide-related thoughts explains the greater risk of future suicide attempts among persistent vs. brief suicide ideators. These aims will be addressed via a longitudinal study of a diverse sample of 150 adolescents, ages 12-19, recruited from two New York City hospitals. Adolescents will be interviewed about the circumstances leading to their suicidal ideation and attempts using a newly developed semi-structured interview. They will also complete laboratory measures of their ability to disengage from suicide-related thoughts. Adolescents (and their parents) will be interviewed again 3 and 12 months later to assess for suicidal ideation and attempts made within the follow-up interval. This research will combine a newly developed semi- structured suicidal ideation interview with structured diagnostic interviews, tests of intellectual functioning, self- report assessments of cognitive biases, and objective measures of suicide-related cognitive biases. Data will be analyzed using multilevel modeling. Understanding patterns of suicidal ideation and their underlying cognitive profiles is a critical step in identifying targets for intervention to prevent suicide in this population. This research has the potential to change how suicide risk assessments are conducted in pediatric EDs by identifying which characteristics of suicidal ideation merit focus in clinical assessments with adolescents.

在青少年期间，自杀企图比生活中的任何其他时间都多。但是，测量 未能理解的细粒度的方面，青少年的自杀思想受到了阻碍 自杀构想从自杀思想到实际自杀行为的过渡。最近的研究 建议知道青少年如何看待自杀（即自杀思想的形式） 频率，持续时间和模式等特征 - 不仅可以预测青少年是否会 继续尝试以后的尝试，但无论他们以前是否有，他们都会多久 自杀企图。但是，当前的自杀思想测量和自杀风险的概念化 倾向于忽略青少年自杀想法的形式。该提议续签得分SC1 格兰特（Grant）试图测试1）是否被认为是在更持久内发生的自杀构想， 长期存在的发作与在12个月内未来自杀未来尝试的短期风险有关 随访期，与简短发作的背景下发生的自杀念头相比； 2）是否慢性 自杀的想法的特征是从与自杀有关 通过实验室措施评估的思想； 3）是否遇到这种干扰和困难的脱离 从与自杀相关的思想中，解释了持久性与简介中未来自杀企图的更大风险 自杀想法。这些目标将通过对150名青少年的潜水员样本的纵向研究来解决， 12-19岁，是从两家纽约市医院招募的。青少年将接受有关 情况导致了他们的自杀想法，并尝试使用新开发的半结构 面试。他们还将完成实验室的措施，以使其与自杀有关 想法。青少年（及其父母）将在3和12个月后再次采访以评估自杀 在后续间隔内进行的想法和尝试。这项研究将结合一个新开发的半 结构化诊断访谈，智力功能的测试，自我的自杀构想访谈，自我 报告评估认知偏见和自杀相关认知偏见的客观测量。数据将 使用多级建模进行分析。了解自杀念头的模式及其基础 认知特征是确定干预目标以防止该人群自杀的关键步骤。 这项研究有可能改变小儿ED中自杀风险评估的方式 确定自杀意念值得重点的特征在与青少年的临床评估中。
